Abstract
The control frequency principle, consisting in the impression of a supra- or infra-audible frequency on a disk record for the purpose of actuating relays and local circuits in order to change views projected by a stereopticon or other means, is described. Two forms of apparatus are presented, the Phonopticon and the Controlophone.
